摘　　要：以腾冲台水平摆资料分析了近年来滇西地区范围内发生的中强以上地震,发现震前资料出现了反映地震孕育过程的异常变化,重点对该地区中强震前短临异常的变化特征进行探讨,为使用腾冲台水平摆资料进行识别以及捕捉地震短临异常,预测地震提供参考依据。The paper analyzes the ground deformation observed by the quartz horizontal pendulum tihmeter at Tengchong seismic station before the moderate and strong earthquakes in west Yunnan in recent years. The paper focuses on the study of the features of the short-impending precursors of the ground deformation before these earthquakes. The results show that the ground deformation obviously show anomaly, which is helpful for determining the short -impending anomaly characteristicsfor the earthquake prediction.
